' a a le am rmes ae i To alley/tom it may concern. Be it known that I, HARPER M. IIUBMAN,

I a" citizen of the United States, and residing, at Detroit, in thecounty of Wayne andyState 1 of lllichigan, have invented "a new and Improved Rim Clamp-Attaching Device, of

which the following is aspecification.

This invention-relates to means for removing the still attached portion ofbr'o-ken lens rims'of eye glasses and spectacles from, the bridge and temple clamps and for securing these clamps to newlens rims, and it con sists in a base provided with a die to hold the bridge or temple end and the rim, a ver tic-ally movable head and bending plates secured thereto adapted to bend the clamps of said attachments toward each other, and a central plate movable between the two other bending. plates for forming a. channel between the ends of these elampsso as. to form agroove to receive the edge of the lens. It

further consists in a pedestal for guiding this vertically movable head and; a lever for moving. it-u-p and down. it also consists 1n a rotatable shaft adapted to be mounted in said pedestal and acur ved blade mounted on the shaft and adapted to spread the clamps of the attachments and remove the remnants of the broken lensrims therefrom. I

Fig. l is a central vertical section'- of a die. with the work in positionjand thejbending. plates :just above the work. Fig. 5 is a simi-.-

The rlms of eye glasses or spectacles are often madeof fragile material, such as torv toise shell and 'celluloid,jand when they be:-

come broken it is diflicult to remove these parts from the clamps -to which the temples being formed with see ifieamn'ofresentment. Patentedhuglo, 1921 a pii cauennied-narch 21, .1921. Serial1 l-o;'-454250. a r

is formed with a small slot to receive the pin ofjthe plunger 6; This f -in theupper end pin 5 is preferably screw-threaded so it may be. readily removedthat these partsmay be connected; At the front of the pedestal 2 are guides 7. for thevertic'a l movable head 8 present device is achjeap and ellicient Which is in the form of a rectangular bar; M

the head being held in position-by means of. a plate 9 secured to the guide s' 7 by. means of thescrews 11 and12, the latterpr e'ferably a wing headand the plate 9 belngformed with. a notch 12 so that it may swing away to the position shown'in Fig. 8.

14 in which is mounted a spring-15 and the W w I A ."l his head 8 is formed with acentral bore reduced lower end 16 of the plunger 6. The

part 16 is formed witha notch 17 which r'eceives the, pin 18.; The front of thehead 8- 1S grooved to receivea plate 19 attached to the plunger 6 by means of the pin 20. 1 The lower end of the plate 19 extends between thetwo :cross plates 22 which-are secured to thehead 8- by means of. screws 23. The

plate 19 is freely slidable. between these,

plates 22,]the latter being held apart. by

verse plates 22 have their lower edges slopihg up inwardly and the plate 1.9 has its lower fedges beveled in. both directions and the lower ends of these three plates are curved to substantially fit the'eye glass rim=A. v y

Mounted in a groove in the base is a die 25 which is preferably formed with two circular notches 26and 27, one having a lateral; extension. 28 to permit the insertion of a bridge' piece and. the otherhaving a ver-; ticalextension 29to receivethe arm 30 of a is placedsubstantially vertically into this means er the 'spacers24c shown in. Fig.1. 1 As shown n F lgs. 1 to 6 inclusive, thetrans,

groove 272 and between the clamps 32. Thev lever 4; is then depressed, bringing the; transverse plates 22 down against the clamps 32 and causing them to bend in toward each other as shown in Fig. 5. This is possible because of the stiffness of the spring 15 which forces down the head 8 and the transverse plates 22. But when the plates 22 can and thereby cause the plate l9'to move down,

relative to the transverse plates 22 as shown in Fig. 6, causingthe upper edges and now the inner edges of the clamps 32 to be crimped down together, as shown in Fig. 6, which not only rigidl secures the attachment to the rim, but also forms a continuation of the groove which is formed on the interior of the rim for the lenses. Q,

It will be understood that where the lens rims A vary greatly in diameter, that addi tional'dies must be substituted and other plates 19 and 22 with proper curvature mounted on the plun er 6 and head 8 but ordinarily a considerable range of variations in diameter will be taken care of by the same set of plates'and dies.

hen it is desired to remove a broken piece of rim from bridge or end, the attachment with the fragment of rim is inserted in the die in the same manner as shown in Fig,

6', but the handle is raised. the screw 12 turned back to permit the plate 9 to be swung to the left and the head 8 is swung out from between the guides 7 to the position shown in Fig. A shaft 35 has a reduced end 36 which is adapted to journal ina hole 37in the pedestal 2, and on this shaft is secured a hook 38, such as shown in Fig. 8 having a sharp point 39 which is adapted tobe swung against the broken end B between the clamps 32 of the attachment. The shaft may be freely turned by means of the handle 10 and the pointed, end 39 when forced through between the clamps 32 not only forces out the broken piece B of the rim, but it also separates these clamps until they are in the position shown in Fig; 4. The.

shaft is then removed, the head8 swung back into position, the plate 9 secured over this head, and a new rim A may then be placed in the groove 27 and secured by means of the plates 19 and 22, as before described.

I prefer to form the dies 25 with indentations 41 indicated in Fig. 10 in their edges to receive the end of the screw 12, whereby the die is held in pre-determined' position. -No particular means need be employed to secure the bridges or ends in position in the grooves in the die, the extensions of these partsln the notches 28 and 29 being sufficient to hold them in position. The details,

sizes and proportions of the'variousparts of this machine all be changed without departing from the spirit of my invention as set forth in the following claims.

the head adapted to engage the clamps of an attachment for the rim, and bend the clamps toward each other, and a plate mounted on the head and slidable between the plates of said pair to bend the inner edges of the clamps to constitute a groove. j 2. In combination, a base, a die mounted thereon and having a groove to receive a lens rim and an attachment therefor including side clamps, a vertically movable head, having a longitudinal bore, a spring mounted therein, a plunger mounted in said bore in engagement with the spring, a pair of spaced beveled plates at the lower end of the head adapted to engagethe clamps of an attachment and bend them around the rim, a plate mounted on said plunger and slidable'between the plates on the head to bend the inner edges of the clamps to conger toward the die.

3. In combination, a die having a groove to receive a lens rim and an" attachment thereforincluding side clamps of a pair of plates to bend the clamps of the attachment around the rim, and a third plate slidable between the first two to produce a groove be tween the edges of the clamps.

l. In combination, a support for the rims of eye glasses and the attachments therefor including side clamps, of a pair of spaced plates for bending the side clamps of said attachment around the rims, and means for bending the edges'ofthe clamps inward.

5. In combination, a support for the rims of eye glasses and the attachments therefor including side clamps, of a pair of spaced plates for bending the side clam s of said attachments around the rims, and means for bendingthe edges of the clamps inward consisting of, apositively operated wedge plate whose operative edge has substantially the for an eye glass lens, a vertically movable head, a'pair of beveled plates resiliently connected tothe head and extending downward therefrom andadaptedjtoengage the'outer sides of the clamps of an attachment for the rim and bend the clamps toward each other, and'a plate rigidly mounted on the head and slidable between the "plates of'said pair to bend'the inner edges of the clamps inwardly to constitutea groove after the first named plates have completed their work and stopped moving.
